Introduction

In this article, we will delve into the world of mathematics and explore a simple yet intriguing problem involving Darla's weekly spending habits. Darla, a diligent individual, spent a fixed amount on Saturday and Sunday for eight consecutive weeks. We will use mathematical expressions to calculate the total amount she spent during this period.

Darla's Weekly Spending

Darla spent $4 on Saturday and $5 on Sunday. To find the total amount she spent in a week, we need to add these two amounts together.

Weekly Spending Calculation

Weekly Spending = Saturday's Spending + Sunday's Spending
Weekly Spending = \$4 + \$5
Weekly Spending = \$9

Total Amount Spent in 8 Weeks

The problem states that Darla spent the same amount for 8 weeks. To find the total amount she spent in 8 weeks, we can multiply the weekly spending by 8.

Expression for Total Amount Spent

The expression $8 \times (4 + 5)$ represents the amount Darla spent in 8 weeks. Let's break down this expression and calculate the total amount spent.

Step 1: Evaluate the Expression Inside the Parentheses

(4 + 5) = 9

Step 2: Multiply 8 by the Result

8 \times 9 = 72

Conclusion

Therefore, Darla spent $72 in 8 weeks.

Discussion

This problem involves basic arithmetic operations, such as addition and multiplication. The expression $8 \times (4 + 5)$ is a clever way to represent the total amount spent in 8 weeks. By evaluating the expression inside the parentheses first, we can then multiply 8 by the result to find the total amount spent.

Real-World Applications

This problem has real-world applications in finance, accounting, and budgeting. Understanding how to calculate total amounts spent over a period of time is essential for making informed financial decisions.

Tips and Variations

To make this problem more challenging, you can introduce variables or change the amounts spent on Saturday and Sunday.
You can also use this problem as a starting point to explore more advanced mathematical concepts, such as algebra and geometry.
